A New Frontier in Wine and Cardiovascular Science: From Bias to Biomarkers

 In this episode of Daily Value, we examine the latest research on wine consumption and its relationship to cardiovascular health. Leveraging urinary tartaric acid as an objective biomarker, a recent study (PMID: 39689849) published in the European Heart Journal provides interesting evidence of a J-shaped association between wine intake and cardiovascular outcomes.

Discussion Points:

• Biomarkers and Bias: The role of urinary tartaric acid in providing a reliable objective measure of wine consumption, avoiding the recall and social desirability biases inherent in self-reported dietary studies.
• Mechanisms of Action: The potential cardioprotective effects light to moderate wine intake (are they real?)
• Dose-Dependent Effects: Insights into the J-shaped curve, revealing cardiovascular benefits with light-to-moderate consumption and increased risk with heavier intake.
